| titleOfInvention | One-step process for preparing mixed substituted 1,2-diacyl-sn-glycero-3-phosphocholines |
| abstract | Single-stage process for preparing mixed-substituted enantiomerically pure 1,2-diacyl-sn-glycero-3-phosphocholines of general formula I <IMAGE> I in which R1 and R2 are different and independently of each other denote a substituted or unsubstituted C1 to C24-alkyl or C3 to C24-alkenyl radical, by reacting 1-0-triphenylmethyl-2-acyl-sn-glycero-3-phosphocholine of the general formula <IMAGE> II in which T denotes a substituted or unsubstituted triphenylmethyl group and R2 is as defined above, with a reactive carboxylic acid derivative of the general formula R1-CO-X III in which R1 is as defined above and X denotes a carboxylic acid radical, a carbonic acid radical, a sulfonic acid radical or the radical of a fused or unfused five-membered heterocycle having at least two N atoms in the ring, in the presence of a protonic acid, of a Lewis acid or of adducts thereof with electron donors, and isolating the resulting compounds of the general formula I from the reaction mixture. |
